Each oppositely disposed pair resident of Cleveland, county of Cuyahoga, bars 2, 2, and 4, a, carries at their lower ends and State of Ohio, have invented a new and a journal rod 5,iFig. 1, which support the as useful Improvement inConveying and D is floor of the conveyer.

This pawl thereforeholdsthe said nut against rotation with the latter .is rotated, the inclination of the by a spring-actuated pawl screw when the ratchet tooth being so arranged that it will pass the pawl-when the rotation of the screw and hence of the nut is in one direction and will. engage and prevent such rotation when the screw is rotated in the opposite direction. In the devicejillustrated .suchnonrotation will be eifectedwhen the screw'is turned in the direction indicated by the arwhich similarly engages a 7 formed in the circumference of the lower flange 1.6, as shown in Fig. 5. This tooth has the opposite direction of inclination and pawl 31 therefore permits rotation of the nut when the screw is rotated in the direction of the arrowin Fig. 4 and preof the screw is in the opposite direction. Near the upper end of-the screw and secured to the frame'is an arm 33, Figs. 4 and5, which lies in the path of travel of the outer arm of point below said a second arm 34 which lies in the path of travel of the pawl 31. It will therefore be seen that when the nut and strap reach a point near. the upper end of their path of movement, the pawl 30 will be: caused to disengage the nut and permit its rotation with the screw 17. Similarly when the said points reach a lower point in their travel, the pawl 31 will be caused to disengage the nut and permit its rotation in the. opposite During such movement the guiding-strip 12 maintains the proper rigidity of the strap.9., hen the nut and strap are in their up permost position, as shownin Fig.1, the floor sectionsfall occupy a' horizontal position.
